Unanswered: Neptune Theme for GXT?

Ist there a plan to realize the theme of Ext JS 4.2.0 for GXT 3.x?
The current themes (blue, gray) have problems with checkboxes and radiobuttons in windows 8, because they get the native look and aren't individualized. So it doesn't look so nice. With the neptune theme everything looks uniform.
